本発明は、照明装置に関する。 The present invention relates to a lighting device.

複数の発光素子が列状に実装された長尺のフレキシブル回路基板と、透光性の軟性樹脂材料から角筒状に形成された長尺の中空チューブと、を備え、中空チューブの内側にフレキシブル回路基板が挿入されてなるフレキシブル発光体が提案されている（例えば特許文献１参照）。 It is provided with a long flexible circuit board in which a plurality of light emitting elements are mounted in a row and a long hollow tube formed in a square tube shape from a translucent flexible resin material, and is flexible inside the hollow tube.

特開２００７−１５０２７１号公報JP-A-2007-150271

ところで、長尺且つフレキシブルな照明装置を、例えば建物内の通路に沿って敷設することにより、誘導灯として使用することが考えられている。しかしながら、特許文献１に記載されたフレキシブル発光体の場合、災害時において停電が発生した場合、複数の発光素子へ電力が供給されなくなるため、誘導灯としての機能を発揮できない虞がある。 By the way, it is considered to use a long and flexible lighting device as a guide light by laying it along a passage in a building, for example. However, in the case of the flexible light emitting body described in Patent Document 1, when a power failure occurs in the event of a disaster, power is not supplied to a plurality of light emitting elements, so that the function as an guide light may not be exhibited.

本発明は、上記事由に鑑みてなされたものであり、停電時において誘導灯として機能させることができる照明装置を提供することを目的とする。 The present invention has been made in view of the above reasons, and an object of the present invention is to provide a lighting device capable of functioning as an guide light in the event of a power failure.

上記目的を達成するため、本発明に係る照明装置は、
可撓性を有する長尺の回路基板と、
前記回路基板に列状に実装された複数の発光部と、
透光性の軟性材料から形成され前記回路基板および前記複数の発光部を覆う透光性部と、前記複数の発光部から放射される光により励起される蓄光材料を含む蓄光部と、を有する長尺のカバーと、を備える。 In order to achieve the above object, the lighting device according to the present invention
A long circuit board with flexibility,
A plurality of light emitting units mounted in a row on the circuit board,
It has a translucent portion formed of a translucent soft material and covering the circuit board and the plurality of light emitting portions, and a phosphorescent portion including a phosphorescent material excited by light emitted from the plurality of light emitting portions. It has a long cover.

本発明によれば、カバーが、複数の発光部から放射される光により励起される蓄光材料を含有する蓄光部を有する。これにより、照明装置の点灯中において蓄光部に含まれる蓄光材料が複数の発光部から放射される光により励起される。従って、例えば照明装置の点灯中に停電が発生して複数の発光部へ電力供給が停止した後において、照明装置の点灯中に励起された蓄光材料から光が放射され、照明装置の点灯状態が継続する。故に、停電時に複数の発光部へ電力供給が停止した状況においても誘導灯としての機能を発揮することができるという利点がある。 According to the present invention, the cover has a phosphorescent portion containing a phosphorescent material excited by light emitted from a plurality of light emitting portions. As a result, the phosphorescent material contained in the phosphorescent unit is excited by the light emitted from the plurality of light emitting units while the lighting device is lit. Therefore, for example, after a power failure occurs during the lighting of the lighting device and the power supply to the plurality of light emitting units is stopped, light is radiated from the phosphorescent material excited during the lighting of the lighting device, and the lighting state of the lighting device is changed. continue. Therefore, there is an advantage that the function as an guide light can be exhibited even in a situation where the power supply to the plurality of light emitting units is stopped at the time of a power failure.

The light emitting elements 22a of the light emitting unit 22 are connected in series or in parallel to each other via a conductor pattern formed on the circuit board 21. The current limiting element 23 is inserted in a conductor pattern formed on the circuit board 21 and limits the current flowing through the light emitting element 22a to a preset size. When a current flows from the DC power supply to the light emitting element 22a through the conductive wire 13 and the conductive pattern, the light emitting element 22a lights up.

The second sub-phosphorescent unit 152 is continuous with the other end of the first sub-phosphorescent unit 151, and the width of the circuit board 21 in the thickness direction gradually increases toward the outer surface 11f of the cover 11.

ここで、カバー１１の外側面１１ｆにおける蓄光部１１５が露出した部分のＺ軸方向の幅Ｈ１は、カバー１１のＺ軸方向の幅Ｈ０の半分以上の長さに設定される。例えばカバー１１のＺ軸方向の幅Ｈ０が５ｍｍ乃至５．６ｍｍの場合、カバー１１の外側面１１ｆにおける蓄光部１１５が露出した部分のＺ軸方向の幅Ｈ１は、例えば２．８乃至３ｍｍに設定される。また、蓄光部１１５のカバー１１の幅方向、即ち、Ｘ軸方向の幅Ｗ１は、カバー１１のＸ軸方向の幅Ｗ０の２０％以上の長さに設定される。例えばカバー１１のＸ軸方向の幅Ｗ０が１３ｍｍ乃至１３．３ｍｍの場合、蓄光部１１５のＸ軸方向の幅Ｗ１は、例えば２．７ｍｍ乃至３．５ｍｍに設定される。 Here, the width H1 in the Z-axis direction of the portion of the outer surface 11f of the cover 11 where the phosphorescent portion 115 is exposed is set to a length equal to or more than half the width H0 in the Z-axis direction of the cover 11. For example, when the width H0 of the cover 11 in the Z-axis direction is 5 mm to 5.6 mm, the width H1 of the portion of the outer surface 11f of the cover 11 where the phosphorescent portion 115 is exposed is set to, for example, 2.8 to 3 mm. Will be done. Further, the width direction of the cover 11 of the phosphorescent unit 115, that is, the width W1 in the X-axis direction is set to be 20% or more of the width W0 in the X-axis direction of the cover 11. For example, when the width W0 of the cover 11 in the X-axis direction is 13 mm to 13.3 mm, the width W1 of the phosphorescent unit 115 in the X-axis direction is set to, for example, 2.7 mm to 3.5 mm.

また、蓄光部１１５は、透光性を有するポリウレタン樹脂、シリコーン樹脂等の軟性材料から形成された基材に蓄光材料を分散させたものから形成することができる。ここで、蓄光材料としては、例えば、硫化亜鉛、硫化カルシウム、酸化亜鉛、一般式Ｍ１−ＸＡｌ２Ｏ４−Ｘで表されるアルミン酸塩から選択される無機化合物の粒子を採用することができる。前述の一般式におけるＭはカルシウム、ストロンチウム、バリウムから選択される少なくとも１つの金属元素である。また、Ｘは、−０．３３以上０．６０以下の範囲の値であればよい。また、賦活剤として、ユウロピウムが添加され、共賦活剤として、ネオジム、サマリウム、ジスプロシウム、ホルミウム、エルビウム、ツリウム、イッテルピウム、ルテチウムから選択される少なくとも１つ以上の元素が添加されてもよい。また、蓄光材料材の平均粒子径は、特に限定されないが、例えば１μｍ以上５００μｍ以下であればよい。 Further, the phosphorescent unit 115 can be formed from a base material formed of a flexible material such as a polyurethane resin or a silicone resin having translucency, in which the phosphorescent material is dispersed. Here, as the phosphorescent material, for example, be employed zinc sulfide, calcium sulfide, zinc oxide, the particles of the general formula M 1-X Al 2 O 4 -X with an inorganic compound selected from the aluminate represented Can be done. M in the above general formula is at least one metal element selected from calcium, strontium and barium. Further, X may be a value in the range of −0.33 or more and 0.60 or less. Further, europium may be added as an activator, and at least one or more elements selected from neodymium, samarium, dysprosium, holmium, erbium, thulium, ittelpium, and lutetium may be added as co-activators. The average particle size of the phosphorescent material is not particularly limited, but may be, for example, 1 μm or more and 500 μm or less.

キャップ１２は、透光性を有する樹脂材料から形成され、有底角筒状の形状を有する。キャップ１２の底壁には、導電線１３を導出するための導出孔１２ａが設けられている。キャップ１２の内側断面の寸法は、カバー１１の断面の外形寸法よりも大きく、カバー１１の長手方向における両端部を覆うように装着されている。 The cap 12 is formed of a translucent resin material and has a bottomed square tubular shape. A lead-out hole 12a for leading out the conductive wire 13 is provided on the bottom wall of the cap 12. The dimension of the inner cross section of the cap 12 is larger than the outer dimension of the cross section of the cover 11, and the cap 12 is mounted so as to cover both ends in the longitudinal direction of the cover 11.

以上説明したように、本実施の形態に係る照明装置１によれば、カバー１１が、複数の発光部２２から放射される光により励起される蓄光材料を含有する蓄光部１１５を有する。これにより、照明装置１の点灯中において蓄光部１１５に含まれる蓄光材料が複数の発光部２２から放射される光により励起される。従って、例えば照明装置１の点灯中に停電が発生して複数の発光部２２へ電力供給が停止した後において、照明装置１の点灯中に励起された蓄光材料から光が放射され、照明装置１の点灯状態が継続する。故に、停電時に複数の発光部２２へ電力供給が停止した状況においても誘導灯としての機能を発揮することができるという利点がある。 As described above, according to the lighting device 1 according to the present embodiment, the cover 11 has a phosphorescent unit 115 containing a phosphorescent material excited by light emitted from a plurality of light emitting units 22. As a result, the phosphorescent material contained in the phosphorescent unit 115 is excited by the light emitted from the plurality of light emitting units 22 while the lighting device 1 is lit. Therefore, for example, after a power failure occurs during the lighting of the lighting device 1 and the power supply to the plurality of light emitting units 22 is stopped, light is radiated from the phosphorescent material excited during the lighting of the lighting device 1 and the lighting device 1 is lit. The lighting state of is continued. Therefore, there is an advantage that the function as an guide light can be exhibited even in a situation where the power supply to the plurality of light emitting units 22 is stopped at the time of a power failure.

また、本実施の形態に係る蓄光部１１５は、カバー１１における、複数の発光部２２それぞれから、前述の基準光度以上の放射方向を臨む第１領域Ａ１以外の第２領域Ａ２に配設されている。これにより、発光部２２から放射される光が蓄光部１１５に過度に吸収されることが抑制されるので、発光部２２から放射される光の利用効率を高めることができる。 Further, the phosphorescent unit 115 according to the present embodiment is arranged in the second region A2 other than the first region A1 facing the radiation direction equal to or higher than the above-mentioned reference luminous intensity from each of the plurality of light emitting units 22 in the cover 11. There is. As a result, the light emitted from the light emitting unit 22 is suppressed from being excessively absorbed by the phosphorescent unit 115, so that the utilization efficiency of the light emitted from the light emitting unit 22 can be improved.

更に、本実施の形態に係る蓄光部１１５は、カバー１１の長手方向に沿ってカバー１１の長手方向全体に亘って配設されている。これにより、例えば建物の通路に沿って敷設した場合、停電時において蓄光部１１５から放射される光により通路全体を照明することができる。 Further, the phosphorescent portion 115 according to the present embodiment is arranged along the longitudinal direction of the cover 11 over the entire longitudinal direction of the cover 11. As a result, for example, when laid along the passage of a building, the entire passage can be illuminated by the light radiated from the phosphorescent unit 115 in the event of a power failure.

また、本実施の形態に係る蓄光部１１５は、前述の第１サブ蓄光部１５１と、第１サブ蓄光部１５１の他端部に連続しカバー１１の外壁に向かうほど回路基板２１の厚さ方向における幅が漸増する第２サブ蓄光部１５２と、を有する。これにより、カバー１１の外壁における第２サブ蓄光部１５２が露出する部分の面積を大きくすることができるので、蓄光部１１５からカバー１１外へ効率良く光を放射させることができる。 Further, the phosphorescent unit 115 according to the present embodiment is continuous with the first sub-phosphorescent unit 151 and the other end of the first sub-phosphorescent unit 151 and toward the outer wall of the cover 11 in the thickness direction of the circuit board 21. It has a second sub-phosphorescent unit 152 whose width gradually increases. As a result, the area of the portion of the outer wall of the cover 11 where the second sub-phosphorescent unit 152 is exposed can be increased, so that light can be efficiently radiated from the phosphorescent unit 115 to the outside of the cover 11.
